Dissertation Title: Change in Nonlinear Dynamics and Spatial Structure of Coastal Socio-Ecological Systems: The Bay of Fundy as Case Study

Advisor: Dr. Andrew Rosenberg

 

Description of Research:

Research in marine historical ecology is demonstrating that contemporary marine ecosystems exist in vastly altered states worldwide. Comparing ocean conditions today and in the past often reveals drastically reduced populations, severely restricted habitats, and radically simplified food webs. Although these trends are dire, a historical perspective can help scientists understand how ecosystems have been transformed over time, and provide baselines from which to measure very long term change. History has additional potential for aiding managers in accurately assessing the current state of marine resources, and in developing future recovery scenarios. Historical marine ecology in Gulf of Maine (GOM) shows the surprising results that a look at the past can provide. Although the modern Gulf is economically productive and ecologically vibrant, research reveals past populations that dwarf presently accepted biomass numbers and an inshore ecosystem that has all but disappeared today.

For my doctoral research, I aim to look at ecosystem structure and dynamics within the Gulf of Maine system from the 1800s forward. To do so, I will be applying novel nonlinear TSA techniques under development at Scripps Institute of Oceanography. These approaches allow investigation of functionally coupled variables and drivers within the system, as well as develop connections within the system and the strength of those relationships. The techniques hold great promise for historical data, as they are completely data driven, require knowledge of the system (that can be found in the historical qualitative text), and have potential to provide proxies for missing data observations as well as entire missing time series. They also allow collapse of the system to fundamental relationships and drivers, thus reducing complexity and data needs for further model building. I will use results from this work to build ecosystem models for the past, as well as explore how that system has changed over time. I am primarily focused on the forage base, e.g. Atlantic herring (Clupea harengus), the anadromous river herrings, mackerel, and sand lance. I am particularly interested in the anadromous fish, and how the loss of these species has affected the inshore GOM ecosystem.

This work is part of a larger initiative to understand the GOM in terms of structure and function. Current work on the contemporary GOM ecosystem (CAMEO group led by G. Sugihara, A. Rosenberg, L. Kaufman, and M. Fogarty) is utilizing these same nonlinear TSA techniques, making my results directly comparable and applicable to current science and management. In addition, Ben Carr, a PhD student with Les Kaufman at BU, is interested in understanding large predators over time – we hope to directly connect our work for a more complete picture. Finally, we also hope to directly link historical results to the Massachusetts Oceans Partnership (MOP) work, as well as build on historical research at Stellwagen Bank National Marine Sanctuary.
